For the first time ever, the surface of a pulsar has been mapped using NASA's NICER X-ray telescope. NASA's Neutron star Interior Composition Explorer (NICER) made the first surface map of the pulsar PSR J0030+0451, a millisecond pulsar located 1100 light-years away in the constellation Pisces. But the surface maps don't look like the traditional magnetic dipole model we're used to. Instead, two - or three - X-ray hotspots were all found in the pulsar's south polar region!

I’m curious- do we know what color neutron stars are?
Man, imagine how good this image would have looked if they used their nicest Telescope instead
Our understanding of pulsars just got a whole lot NICER!
I see what you did there.
You just had to say that. 🤦🏻
Possibly one of the weirdest things in the universe just got weirder! Thanks for sharing this with us, Christian. My favourite part was dissecting how the hot spots were mapped and possible reasons for their pattern. I learnt a thing!
The weirdest thing about the universe has to be. Why ?
You're channel is amazing, you're the sole reason I have the motivation to pursue a degree in astronomy, you make everything you talk about so clear and easy to understand and I love it, thank you
Thank you Aaron, I'm so delighted and flattered! Now go make me proud.
@@LaunchPadAstronomy astronomy is the best part of science
You might want to work on that grammar, Aaron, if you’re pursuing a degree of any sort.
@@Lagmire you know that not everybody on the internet may be a native english speaker right?
@@Lagmire You seem kinda obnoxious.
To Map a Pulsar with this level of detail is absolutely amazing . It is difficult for me to imagine how matter is behaving under so much pressure n high temperature .
Thanks Christian for sharing another awesome video . 🖖
Yeah, it's pretty mind-blowing stuff. Appreciate the kind words as always!
Is it possible that the wacky magnetic fields could be partially caused by them dragging against the interstellar medium? The pulsar’s magnetic fields are so strong that they rip material off of the pulsar and slam them back into it. Is it possible that these fields are so tangible that them dragging against the interstellar medium causes them to be “pushed” to a relatively similar location?
"Super spinning power zombie bar magnets" - That was the best description of a neutron star I've ever heard.
lol, thanks!
It is also an unreleased Rob Zombie album
@@TimRobertsen 🤭🤭🤭🤭
😂😂 yeah that was sooo good, LoL
That's an awesome description! LMAO
For such a small channel, the content is of an unusually high quality! I love it! Also, this gentleman puts so much soul into these clips that I stuck with him through every sponsorship ad...
Wow, thank you for the kind words and especially for tolerating the ads! They do help!
Great video as always Christian, thanks.
My pleasure, and thank you!
You're the best at explaining things and my favorite
Thanks. To quote my favorite stoic, "Fascinating!" tavi.
I like the Grateful Dead icon in the background :D
I was born and raised a Deadhead.
@@LaunchPadAstronomy oh fantastic! I raised myself as one :D
Just found you & your channel 6-21-20 2am. I really like you presentational style, I'm subscribed. Great stuff, thank you!
Thanks, I'm glad to have you along for the ride!
You deserve so many more subscribers!
Oh thank you, I'm working on it! :)
First time i've seen your videos pop up on my suggestion feed. Good stuff! Quick thought on the subject at hand. Is it possible we're seeing an effect from frame dragging? It's more slight than a black hole, sure. But would still have an impact. What I find of even greater curiousity is the VERY specific angle it's escaping from. Maybe the EM can only 'sneak out' at specific angles.
always a pleasure to watch these videos. what if the differences in the observations can be chalked up to almost refraction and their specific angle or view, since pulsars can bend space time and thus light there could simply be 2 poles we can see and one on the opposite side/ far side. we could only be seeing just one side of the pulsars yet 2 flashes each from 2 of the same polarity poles. its not uncommon for several poles when dealing with planetary + electromagnetic fields.
Excellent content, very informative. Thank you Launch Pad Astronomy.
My pleasure!
0:42 We learned that they formed from a Looney Tunes cartoon intro i think.
I just love the fact that they are the biggest known atoms in the universe. At least to humans, so far.
Another excellent report Sir. Thank you.
Glad you liked it!
my favourite part of 2020 is im here learning about pulsar's and there are other people in the world debating whether the earth is flat or not...
i dont understand most of this ill be honest but it is very interesting, thank you for your videos I really enjoy them . and I some times learn stuff
My pleasure, my friend!
Ah, now I get what NICER does!
Have you talked about how LIGO set a limit for how smooth neutron stars must be?
I discussed LIGO's detection of black hole mergers but haven't talked about its neutron star work, yet. But that's not a bad idea!
I Love Astronomers. They do the equivalent of telling you the wight of the snow on a mountains top from a rice corn that grew on it´s foot! And I love it!
Very interesting guesses, thanks for sharing.
Pretending that my love of astronomy and physics brought me here, when the truth is I thought this was going to be a video about Elite Dangerous.
Shhhhhh.
Wow I gotta say... The reconstruction is much nicer than I expected xD
XD
This was detailed and great
Damn sir! That sponsor transition was smooth. Great video.
LOL thanks, I appreciate it!
I'm often in awe of stuff like this just because somebody said, hmm, this thing is hundreds of light years away and made of exotic matter we don't totally understand, I bet we can figure out what it's interior looks like. Then they went and did it.
It is so crazy difficult to wrap my mind around the possibility of seeind the far side of something just because it is so dense it warps space-time... O.o
The Universe is a strange and interesting place :)
Sadly, when I was younger I thought pulsar actually had pulse, pulsating energies or something. Unlike flat-earthers, when I learn something, I stick with reality regardless if I agree or disagree.
I always though the actual shape of the earth was better than a frisbee. I mean, it can bounce off a wall back to us, just maybe!
@eric vosselmans Because I'm not a islamophobe bitching about other people's religion on the internet.
@eric vosselmans Because there are laws against discrimmination by religion. There isn't anything protecting flat earthers, because they're just stupid.
Bro the universe is flat. Im woke
Thank You!
Is it just me or does this remind you of vids the teacher showed in school when she didn't want to teach? I ain't complaining, I'm happy about it. I love this guy
lol, well thanks Darren :)
Awesome as usual, man.
🤜💥🤛
Thanks man!
First time watching your channel. Absolutely awesome video. Great job. and I CAN NOT believe you have the Grateful Dead and Hitchhikers guide in the background...lol. That alone deserves a "Like". Consider me subscribed.
Appreciate having you along for the ride!
Solid!
Top KEK!
Nice, ive bin donating cpu for this project via boinc.
well done?
Love the fact he's a deadhead, that's awesome. I grew up on that music! I'm binge watching all his uploads, format never changes, direct information with a discussion on how it works. Great channel.
Thanks! The GD book is part of a tribute to my late mother, who raised me on the Bus.
That's one of the most amazing things I've heard. Sounds a bit like my mom, she took me to my first jethro tull show when I was just 4. I lost her 6 yrs ago to a stroke. You are an amazing person, pls keep doing this! You have a gift that sucks ppl in, it's rare and you should be proud of what your teaching, glad I found your channel.
Sounds like both of us were raised right. Thank you so much for the kind words, I truly appreciate them.
I can't believe I just found this channel. It's excellent.
Q:What is a pulsar?
Me: A star on crack.
Ba dum dum PSSSH 🥁
when i think "boy we really know alot".....i just look up in the night sky and think "shiet...."
Can NICER only do this type of study on "nearby" pulsars?
Pulsars never stop to surprise!
Agreed!
Fascinating!
indeed!
I think this might have been what I seen about an hour ago. I've seen this before (I think this past fall) and did a LITTLE googling, but didn't find anything similar. When I noticed it tonight, after the second rotation (that I saw), I tried to quickly get my phone out and capture it. Sadly, only one more rotation was visible to me, but I did manage to capture that last one.. JUST IN TIME too. I'm just assuming this was a pulsar.. it's the only thing that comes close to the description of what I have seen.. TWICE IN ONE YEAR!
Great channel and superb presentasion. I even understood stuff 😁
Thanks, I'm glad you enjoyed it!
I will say Magellan tv actually isn’t bad- tried it out and it certainly fits in my nerdy catalogue
I'd love an big absorvatory with elaborate scientific equipment, a human scientific contingent, ample resources, taking a few years to observe these stellar remnants up close. Like, throwing iiron ingots on the surface of the neutron star. Maybe we can ask aliens for a ride there.
...all this from a safe distance...
Good information 👍
So the minimum mass of a pulsar could be the Chandrasekhar limit minus the binding energy, which in a neutron star is huge?
Could it be gravitational effects causing this? Could the other two be infact the same pole warped by spacetime like an Einstein cross. Maybe some sort of lensing effect?
I have flown to a pulsar in the the constellation Draco. They are really no big deal. I stopped it’s rotation with a hello kitty toy magnet and then walked on its surface.
Now that’s some cold hard science 👌 (Or potentially hot and extremely dense)
Would two poles in the same hemisphere actually affect the actual shape of the pulsa or give it a rotational wobble.?
I'm ready to learn
Weird the previous video is right next to dhus one as the watch next area and weird that iron,which is attracted to magnetic field creates one
Very interesting, but which bit is the "Unbelievable" bit?
It's a fine channel brother.
fascinating
isnt that rotation speed faster than speed of light ?? same for coronal arcs of sun ??
I could demagnetize a pulsar with a Hello kitty magnet.
I don't know how i just found your channel today
I'm glad you did!
Harmonic poles related to mass and resonance
Hi Christian,Weird,Some Friends and I Were Just Talking About Pulsars,Weve Had Some Great Nights On Getting Data Of The SN In M.61..Im Excited To Get About Another Hour and Get Everything Processed.Great and Informative Video..Happy Days And Clear Skies❤️🔭❤️,and Im Telling My Supervisor That My Personal Astronomer Told Me To Stay Home😂🤷🏼♀️🤷🏼♀️
Awesome. Good luck on the supernova!
Launch Pad Astronomy ,Thank You Very Much,Were All Clouded Up Now,So My Solar Viewing Just Turned Into a Nap😂😂Have a Great Day,Be Safe,and God Bless❤️🔭🌏🙏🏼
What kind of telescope object miniature is on his desk behind him on the right??
It’s the Giant Magellan Telescope.
I wish I could stand on one and look up at the stars in the sky as I'm spinning around like that
From the results, it looks like a standard multistream dynamo consensus field, much similar with our observations of the solar magnetic field and even earth's field. Not a single equatorial stream, but multiple "rivers" of electrons in a superconducting mantle region and events when the entangled field lines disconnect.
Overall, I'll editorialize in saying, that's a really rough neighborhood to try to live in. ;)
Thank you. I signed up.
Welcome, and glad to have you along for the ride!
I have a question. If the magnetic field from a pulsar emanates from the poles then the beam of EM radiation should point in a fixed direction. How is it then that the beam behaves like a light house
Hi Andy, The beams emerge from the magnetic poles, which in the traditional model are thought to be similar to those of a bar magnet. But the "bar" is tilted with respect to the rotational poles of the pulsar, so the beams rotate with the the pulsar as a lighthouse. Hope that helps!
The best theory i have is that the universe is like a spider web and these pulsars are spinning them, since singularity would mean end of existence for anything beyond the even horizon... unless you are somehow spun out of the black hole with the rest of "real" matter.
Hello, all your videos are really interesting, but you'll want to check your microphone, on this one there is a back noise (quite acceptable), but on another one I couldn't finish it as the sound was like if you spoke in a cooking pot ^^ (really annoying :/ )
Thanks for all the shared knowledge :)
Thanks and sorry for the lousy audio. I’ve been struggling trying to get better at it. Hopefully my more recent videos sound better. Cheers!
I think the statement of "mapping" it means something different to the mappers than it does to me. Because we all know that the "mountains" on a neutron star are a fraction of a millimeter tall, so I don't buy the premise that such a thing as micrometer tall features could be measured from hundreds of light years away. Oh well I guess I'll watch the video to see wtf he's talking about in this 'map'.
so we measured approx 1km variations on an object 1000 ly away
yet, we can't even observe Pluto from Earth in detail, right?
On the subject of life appearing on the surface of a pulsar, you can read Robert Forward's hard science novel "Dragon's egg". :)
Loved it and Starquake!
Milliseconds is the rotational speed of the full star or of the “jets” speed?
That's the rotation period of the star itself. The jets are moving at nearly light speed.
Launch Pad Astronomy THanx a lot! I knew jets travel at near light speed, my doubt is about “what is the thing/phenomenon that really rotates”. Since we didn’t even have a precise rate for our Sun, and the one we have was estimated by observing sunspots, and we know not all the body rotates at same speed.
Do you think is correct/fair to assume +10Hz as radiation field’s rotating rate and not necessarily full body’s rotation?
(Yep, I’m having kinda issues with some science’s assumptions. Appreciate your patience/understanding. Maybe is just the core or the surface or surface’s ecuator)
What is the interstellar medium? Is it gas and dust? Please explain.
Yes, that's exactly what it is. Space isn't completely empty :)
I like the Grateful Dead Scrapbook inthebackground... Somehow that's very appropriate
Thanks. It’s a tribute to my late mom. She raised me a Deadhead.
@@LaunchPadAstronomy Sorry to hear that! She must've had great taste. I play in a band called Antwerp Deadheadz, we mainly play country versions of G. Dead songs, taking them back to the roots so to speak... Here's a clip for you to enjoy: czcams.com/video/0bSpXakVEM8/video.html
Have a nice day and keep up these videos, they're great!
Wow , you guys are great! I loved that interpretation of Samson & Delilah. If I'm ever in Antwerp, I'll stop by one of your gigs!
installing a add-on to the space station
"don't worry, it would've been rocket science"
Does this mean we wouldn't be able to use pulsars as a "pseudo interstellar GPS" for navigation given their new found unpredictability?
No we certainly could use them, but we'd have to update our "GPS" database to account for changes.
You sure the two groups observing the Pulsar are watching the same one? Since their sizes and masses and even the placements of the magnetic field line spots are different?
They're really not so different in the sense that they both predict one or more magnetic poles in the southern hemisphere of the pulsar, as opposed to one model showing the traditional dipole model and the other showing something completely different. If that were the case, then confidence in the data or the analysis would be much lower.
1:21 Any chance that inner core might actually be a quark star?
oh God whats that haha
there are some recent studies proving/suggesting that the quark matter is real, and that a large core of almost every neutron star is made of quark matter, in a superliquid state.
please explain why every computer model we have ever made says a super nova due to collaps and then rebound energy never actually goes super nova in the models! The models say there is not enough energy to cause the rebound explosion! ???????? Plasma physics need to be used to explain what is really going on here not gravity based cosmology!
So blackholes are the monopole we been looking for, interesting.
Hey, I used to have that "Space Places" book, once upon a time! Last time I had it in my hands was probably well over 20 years ago. I remember it being EXTREMELY heavy. Probably one of the heaviest books I've ever owned. I can only think of maybe two others.
Anyways, my religious parents are ... not into the whole "space thing" ... so they tossed it. I really miss that book. =(
I'm sorry to hear about your loss of the book and the views of your parents. That must be so hard to put up with and still maintain a functioning relation with them.
Very interesting, thank you. You got a like and a subscribe for the Grateful Dead logo!
Thanks Paul, and I'm glad to have you along for the ride!
I wonder how spinning anything makes a magnetic field? If they were spinning 1,000’s of times a sec, wouldn’t that counter the inward gravitational weight from its mass? Spec Relativity says a particle can’t distinguish the difference between the forces of gravity or force of motion?
My name is Mormon Unprepared. Nice video.
Does a galaxy have a magnetic north and south?
4:06 Woah woah woah... Pulse "Profile" Modeling?!
There has to be a better way!
The theory of GR doesn't forbit that , gravity will still be strong enough that light won't escape , in just really uncomfortable with the idea of event horizon and singularity
4:44 did i saw a sphere there? no no no i protest with all my very little brain. It must be flat, like my electroencephalogram !!!.......
The core of a Neutron Star is made up a fluidic mass that fluctuates between normal mass and Hexaquarts. However, Neutron Star don't have the mass of conditions to maintain the Hexaquarts which is constantly breaking down do to the weak gravity.
What's a hexaquart? A gallon and a half?
@@acr08807 It's also lemony fresh
Well this blew my brain.
Glad to be of service :)
What if in the middle of a neutron star is black hydrogen?
Wait what if black holes are quark stars , but stranger , some new form of "energy"
And since individual quarks are undetectable the whole system because it is so compact behaves like 1 quark into semi quantum state
Imagine how much energy would come out if a black hole ripped it apart
I'm trying to imagine how a black hole rips apart in the first place :)
If it's realigning its magnetic field,what could cause it?
Interesting question and the short answer is 'I don't know' :) It's not clear why Uranus and Neptune's magnetic fields are misaligned either but it's thought to have something to do with differential rotation (equator rotates faster than the poles). The question is if neutron stars can have a similar kind of differential rotation even if they're more dense than anything on Earth?
Can a neutron star/ pulsar have a mass greater than 1.44⊙ ?
Yes it can. They're thought to range up to 2.16 solar masses.
if they are the result of a supernova where is the evidence for said supernova?
do all pulsars sit in the middle of matter ejected by a nova?
maybe it is a pulsar with a black hole inside. maybe caused by the shockwave?
